Today I am supposed to start, according to glow. But I always chart my periods and yesterday I was suppose to start. Haven't had a single PMS symptom and it's getting sketchy. My boobs always hurt a week before my period and I feel nothing. No cramps, just nada. This is the first time I feel absolutely nothing. Can someone help me out here? I know I ovulated on the 6-7 cause its always painful and dull for me.
